Google Makes AdSense Faster Slowly

Google promised in December 2009 to make the popular ad serving platform faster. Especially after promising to incorporate site speed in rankings and then webmasters noticing that their site speed was being negatively impacted by Google AdSense.

Google said:

AdSense ads, like any element on a webpage, usually contribute to the time the page takes to load. Last year, we ran tests that showed AdSense adding 12% on average to the time it took to load various pages from top web sites, so we set out to make this better. We've now developed a new ads delivery technique to improve the speed of websites that display AdSense ads, so that it doesn't slow down your page content. We're very happy to announce that we've eliminated this slowdown for the majority of websites and for a number of browsers, and are seeing pages load as much as a second faster than before.

What do you as a publisher with AdSense ads on your site need to do? Nothing. Google has done it for you. They basically made them load as iframes with the existing code, which means your page will load independently of the AdSense, thus not slowing down your web site.
